A Tier 2 Supplier is a company that provides products or services to a Tier 1 Supplier, which directly supplies to the original equipment manufacturer (OEM). Tier 2 Suppliers typically produce components or materials that are essential for the final product but do not interact directly with the OEM. These suppliers play a crucial role in the supply chain, ensuring that Tier 1 Suppliers have the necessary resources to meet production demands. They often specialize in specific materials or processes, contributing to the overall efficiency and quality of the final product delivered to consumers.
